Reasons [5]

"You failed the test I prepared for you."

Susan couldn't understand what Eth was saying. Was she undergoing a test?

"What test?"

"Did you think I didn't know that you were watching my moves all this time?"

'If you did. You are absolutely correct.'

Susan's eyes widened when she heard him. This was the first time Eth saw her expression changing.

'That's some otherworldly level of beauty, alright. But you can't trick me with your charms!'

Eth rested his cheek on his right fist.

"You began tailing me after I killed the boar. Since it seemed that I had a plan to deal with my teammates, you decided that tailing me would be interesting."

Eth spoke without hesitation.

But of course, he was lying. Though, this was pretty easy to deduce after knowing her personality and comparing it with what happened in the exam.
